Here are some more samples (2ch 96khz, 5ch 48khz, 5ch 96khz):

[Dennis]

Any progress on this?
FFmpeg is so close to supporting my entire audio library now.
Thanks!

[Dennis]

Still very interested in seeing this come to fruition.
Has there been any development on this?

$20 Bounty

[Dennis]

Who ever fixes this can collect on both of these bounties:

​https://www.bountysource.com/issues/1414845-wmalossless-support-24bit-depth

However, the bounty should be dependent on this issue being fixed as well:

[Dennis]

Just checking in on this.
So many projects use FFmpeg, this would solve a major hurdle for me.

Still an issue:

File encoded from mp3 in foobar2000+WMAEncode.exe (​https://hydrogenaud.io/index.php/topic,90519.0.html)
I chose the 16-bit, but encoder made a 24-bit. I think this is due to the fact that the original file was a strong clipping.

It looks like ffmpeg's wmalossless decoder (24bit 44khz mode) has problems with high amplitudes:

org.wma - file encoded from org.wav
org_0_99.wma - file encoded from org_0_99.wav

ffmpeg -i org.wav -af "volume=0.99" org_0_99.wav

What's also interesting: org.wma size vs org_0_99.wma size.

Any known decoder that decodes this?

[ami_stuff]

Replying to richardpl:

Any known decoder that decodes this?

It decodes correctly with original MS codec. I don't think that there is any other open source implementation.

[Elon Musk]

I know that already, looking for executable/dll.

[ami_stuff]

wmadmod.dll?

​https://samples.ffmpeg.org/drivers32/all-20110131/

[Dennis]

Here is the last version of Windows Media Encoder:
​https://www.djxmmx.net/ffmpeg/4134/
Two EXEs for installation.
Alternatively, I copied the installation directory from the 64-bit version so you can examine the DLLs or EXEs it installs.

M$ discontinued the Windows Media Encoder so that's why I linked to it from a private server.

Can I get wma lossless files with fully 24bit samples, not just padded samples? Original first link is not more useful.

I converted this file:

to wmalossless

​https://www.datafilehost.com/d/3564cbb8

Lossless samples also available here:

Converted with M$ encoder from DVD Audio source.

[Elon Musk]

Can I get decoded output too, in 24bit pcm?
The thing ami_stuff posted is resampled thus useless to compare bit exactness.

[Dennis]

Sure, check the WAV files I just put in there.

[Elon Musk]

What you used to decode those?
FFmpeg decoder with my patch decodes same thing as wmal2pcm and 09 sample have noise at end but your decoded output doesnt.

[Dennis]

Creative Audio Converter (From The Creative MediaSource software pack [Creative Labs]).

[Elon Musk]

Have a link from where to download it?

[Dennis]

Sure...
I put it in that folder for you.

[Hendrik]

For comparion sake, I converted the 09 track to WAV and FLAC using the Microsoft decoder.
​https://files.1f0.de/samples/09.wav

[ami_stuff]

stereo files seems to decode correctly with patch from ffmpeg-devel, but multichannel files not.

[Elon Musk]

Then please upload multichannel files (with source ones too).

[ami_stuff]

​https://www.datafilehost.com/d/a92e84c0

[Elon Musk]

Doesn't same happens with 16bit files?

[ami_stuff]

for 16bit there is only one encoding mode (44khz, 2 channels)

[Dennis]

Right, WMA Lossless will only do multichannel at 24-bit.

It would be very nice if you guys could isolate that audio which is causing problems and encode only it, so its length is very short. This would speedup debugging tremendously.

Funny, looks like 16bit decoding is buggy too.

[Elon Musk]

This was unrelated bug that I just fixed. So still need that sample(s).

[Elon Musk]

Actually the only remaining issue AFAIK is not bitexactness of "09 - Walk On By.wma" with latest reference decoder.
Our decoder decodes same output as WMAL2PCM.exe program.

I think noises in 24bit decoding are finally fixed.

[ami_stuff]

There seems to be one difference in the output of 2ch 24bit 96khz mode compared to the original codec - file is amplified a lot:

If you happen to know how to isolate this with ffmpeg

ffmpeg -i t96.wav -ss xx -t xx out.wav

then I can encode only this fragment of the audio.

[ami_stuff]

and here are 2 differences (2 data blocks are different in the output pcm compared to the output from original codec):
